Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] A buckle bending angle detection mechanism, combined with Figure 1 As shown, the system includes a workbench 1 and a control box 7. The workbench 1 has support legs 2 at its bottom and an angle detection mechanism 4 on it. The angle detection mechanism 4 is used to detect the bending angle of the buckle. A positioning mechanism 5 is also installed on the angle detection mechanism 4 to position the buckle at the bending point. A clamping mechanism 6 is also installed on the workbench 1, located to one side of the angle detection mechanism 4, and is used to clamp the buckle from both ends. The control box 7 is located on the workbench 1 and has a touch screen display 71 for human-machine interaction. The touch screen display 71 is electrically connected to a PLC controller, which is located inside the control box 7. The PLC controller is electrically connected to the angle detection mechanism 4, the positioning mechanism 5, and the clamping mechanism 6, respectively, thereby achieving automatic control of the buckle bending angle detection.

[0020] The angle detection mechanism 4 includes a turntable 41 horizontally mounted on the worktable 1. The turntable 41 is rotatably connected to the worktable 1 via bearings with rotating inner rings and stationary outer rings. A rotary motor 42 is connected to the bottom of the turntable 41 and is mounted on a support plate 3 located between the support legs 2. The rotary motor 42 drives the turntable 41 to rotate, and an angle sensor is mounted on the rotating shaft of the rotary motor 42 to detect the rotation angle. A measuring column 43 is erected on the upper surface of the turntable 41. The measuring column 43 is offset from the center of the turntable 41 and moves between the two sides of the latch as the turntable 41 rotates. A pressure sensor is mounted on the side wall of the measuring column 43 to monitor whether the measuring column 43 is in contact with the edge of the latch. When the rotary motor 42 drives the turntable 41 to rotate, the measuring column 43 moves from one side of the latch to the other side, and the angle sensor detects the rotation angle.

[0021] like Figure 2 As shown, the upper surface of the turntable 41 is provided with several threaded blind holes 411, and the bottom of the measuring column 43 is provided with an external thread that matches the threaded blind holes 411. The measuring column 43 is adjustablely mounted on the turntable 41 through the external thread and the threaded blind holes 411, thereby improving its applicability.

[0022] like Figure 3 As shown, the positioning mechanism 5 includes a concentric column 51, which is erected on and concentrically positioned on a turntable 41. The turntable 41 is rotatably connected to the bottom of the concentric column 51 via a bearing where the inner ring does not rotate and the outer ring rotates. A positioning mounting plate 52 is horizontally positioned on the top of the concentric column 51. Two opposing upright plates 53 are erected on the positioning mounting plate 52. A horizontally positioned positioning positive and negative lead screw 54 and a positioning guide rod 55 are positioned between the two upright plates 53. The two ends of the positioning positive and negative lead screw 54 are rotatably connected to the upright plate 53 on the same side. A positioning motor 58 is connected to one end of the positioning positive and negative lead screw 54, which is mounted on the positioning mounting plate 52. Positioning mounting seats 56, which are slidably assembled with the positioning guide rod 55, are connected to the two lead screw nuts of the positioning positive and negative lead screw 54. A positioning rod 57 is erected on the positioning mounting base 56. The positioning rod 57 is used to abut against the side of the buckle bend. The midpoint between the two positioning rods 57 is on the same vertical line as the center of the turntable 41. A positioning pressure sensor is provided on the side of the positioning rod 57 that contacts the buckle bend. When the positioning motor 58 drives the positioning forward and reverse screws 54 to rotate, the two positioning rods 57 move towards each other and clamp the buckle from both sides of the buckle bend, so that the center of the buckle bend is concentric with the turntable 41, thereby ensuring that the intersection point of the inner sides of the buckle is concentric with the turntable 41.

[0023] A gantry 59 is provided on the positioning mounting plate 52. The gantry 59 spans the positioning positive and negative screw rods 54 and the positioning guide rod 55. The gantry 59 is used to support the buckle from the bottom of the buckle bend.

[0024] The clamping mechanism 6 includes a stand 61 erected on the workbench 1. A horizontally positioned telescopic cylinder 62 is mounted on the stand 61. The telescopic rod of the telescopic cylinder 62 faces the positioning mechanism 5 and is connected to a clamping mounting plate 63. A horizontally positioned fixed clamping plate 64, with its upper surface flush with the upper surface of the gantry frame 59, is mounted on the clamping mounting plate 63. A movable clamping plate 65, slidably assembled with the clamping mounting plate 63, is horizontally positioned above the fixed clamping plate 64. A vertically positioned telescopic cylinder 66, longitudinally mounted on the clamping mounting plate 63, is connected to the top of the movable clamping plate 65. A clamping pressure sensor is mounted on the lower surface of the movable clamping plate 65. When the telescopic rod of the horizontal telescopic cylinder 62 extends, both ends of the buckle enter the clamping opening formed between the fixed clamping plate 64 and the movable clamping plate 65. The vertically positioned telescopic cylinder 66 drives the movable clamping plate 65 to move downwards and clamp the two ends of the buckle.

[0025] A translation guide rod 67 is provided on the clamping mounting plate 63. The translation guide rod 67 is horizontally set and slidably assembled with the upright frame 61 to ensure the stability of horizontal movement.

[0026] The input terminals of the PLC controller are connected to the output terminals of the detection pressure sensor, angle sensor, positioning pressure sensor, and clamping pressure sensor, respectively. The output terminals of the PLC controller are connected to the controlled terminals of the rotary motor 42, positioning motor 58, horizontal telescopic cylinder 62, and vertical telescopic cylinder 66, respectively, thereby realizing the automatic control of the mechanism. The detected bending angle data is displayed on the touch screen 71. The specific bending angle is equal to the value detected by the angle sensor plus the angle formed between the two tangent lines that start from the center of the turntable 41 and are tangent to both sides of the measuring column 43. The PLC controller adds this fixed angle to the value detected by the angle sensor to obtain the bending angle.

[0027] The working principle of this utility model is as follows:

[0028] Positioning phase:

[0029] The buckle bend is placed between the two positioning rods 57 with both ends of the buckle facing the clamping mechanism 6. The PLC controller controls the positioning motor 58 to drive the positioning forward and reverse screws 54, so that the two positioning rods 57 move inward synchronously to abut the two sides of the bend. The positioning pressure sensor monitors the pressure in real time. When the set threshold is reached, the PLC controller stops the positioning motor 58.

[0030] Clamping phase:

[0031] The horizontal telescopic cylinder 62 pushes the clamping mounting plate 63 to the end of the buckle, and the vertical telescopic cylinder 66 drives the movable clamping plate 65 to press down. The fixed clamping plate 64 cooperates with the movable clamping plate 65 to clamp the buckle. The clamping pressure sensor monitors the pressure. When the pressure reaches the set threshold, the PLC controller stops the vertical telescopic cylinder 66.

[0032] Angle detection stage:

[0033] The rotary motor 42 drives the turntable 41 to rotate. Based on the contact pressure between the measuring column 43 and the edge of the buckle monitored by the detection pressure sensor, the rotary motor 42 is controlled to start and stop, so that the measuring column 43 moves from one side of the buckle to the other side. The angle sensor detects the rotation angle, and the PLC calculates the bending angle based on the detected rotation angle and displays the result on the touch screen.
